MENDHAM - Gov. Chris Christie says that Donald Trump is not a racist.

The former Republican presidential candidate and his son, Andrew, who are delegates for Trump, voted Tuesday at the firehouse in their hometown of Mendham for the primary election. Their names are on the ballot with Trump's.

Trump has been criticized for saying U.S. District Judge Gonzalo Curiel cannot judge him fairly because he is of Mexican heritage and Trump plans to build a wall with Mexico.

"I know Donald Trump. I’ve known him for 14 years. And Donald Trump is not a racist,” Christie said. “The allegations that he is are absolutely contrary to every experience that I’ve had with him over the last 14 years.”

However, not all of Trump’s supporters are on board with his comments. House Speaker Paul Ryan recently endorsed Trump but spoke out against the comments.

"I disavow those comments. I regret those comments that he made,” Ryan said. “Claiming a person can't do their job because of their race is sort of like the textbook definition of a racist comment.”

Ryan does say that he still stands by his endorsement of Trump, despite the comments.

Trump released a statement about the situation that said, “I do not feel that one's heritage makes them incapable of being impartial, but, based on the rulings that I have received in the Trump University civil case, I feel justified in questioning whether I am receiving a fair trial.”

Voter turnout for Tuesday’s primary election could be light because Trump has already got the number of delegates needed to clinch the nomination. 

An Associated Press count Monday found that Hillary Clinton has commitments from the number of delegates needed to secure her party's nomination.
